% Style file for LaTeX2e

% This package defines the macro \lastpage which contains the (string)
% value of the page number of the last page of the document.  The document has
% to be processed at least twice for this label to be defined.
%
% This package defines a page style is similar to plain, but with the page
% number expressed as "N / M", where M is the total number of pages.  This
% package invokes \pagestyle{NofM} to make this the default page style.
